The song and the music video are wonderful. In my own the understandig, the song tells that in love, we risk everything to be happy even along with it is pain. You will feel the true meaning of happines when you are with each other. You are happy when you laugh together, happy when you hold hands, when you hug. But how about when you are not with him and you perfectly know that he is with the arms of somebody else. In the arms of someone whom he truly loves. It is painful, it hurts. But you are willing to swallow the truth and all the pain just to make your self feel happy. How ironic!
